Compost or Soybean Meal?
Come fall, I'd like to work on getting our lawn in better shape. It is quite thin and is being invaded more and more with crabgrass.
My plan is to overseed this fall and then apply corn gluten meal in the spring.
My question is, should I apply compost before I overseed or would just putting down soybean meal work? Our current soil is low in organic matter and is very sandy, so I imagine that compost would be the best, but at 12,000 square feet, that is a lot of compost! (assuming 1 yard per 1000 square feet). Soybean meal would be easier as I could do maybe 150 pounds worth but that's obviously not that much organic matter, so would that not really help much?
I'm not looking for a perfect lawn, just one that is more filled in and not thin.
